The objective of this present investigation is to design a composite corrosion-inhibiting admixture system comprising of both mineral and chemical admixtures and to evaluate its performance in concrete under macrocell corrosion conditions. The newly designed corrosion-inhibiting admixture system performed very well in chloride-contaminated concrete. Steel embedded in ordinary portland cement suffered severe corrosion. In concrete incorporating the designed admixture system, steel showed a 10-fold decrease in corrosion rate of steel embedded in concrete under accelerated macrocell corrosion conditions. The compressive strength of mortars was not affected by adding the designed admixture system.
